I am facing this the same issue on two servers.
The network manager getting crash time to time. Initially, tech managed to resolve by installing network manager dependencies, but it happening again.
OS : AlmaLinux v9.4.0 => then converted to => CloudLinux v9.4.0
Hardware : CPU : Intel(R) Xeon(R) E-2378 CPU @ 2.60GHz
I have other servers on the same version of OS, but both servers with the same CPU facing the extract same issue. I am not sure where it related to.
Attached the screenshot of Network Manager status when the interface is down.
